Praying mantises and particulate matter



Sprouted wheat seed which we used to make Essene bread. This is bread which uses only one ingredient, and is cooked at a very low temperature - it can even be cooked by the sun. Our first try was not a great success as we had difficulty grinding the "flour" fine enough.


Hard to see, but this was our experiment in particulate matter. There are 4 materials in the bags: wood, wheat, salt and sugar, each material having a large, medium and small particle size. The boys were challenged to identify the materials. We sorted them into materials and particle size, discussed how the various particle sizes were created, and why they might be needed (eg wheat seed for planting, cracked wheat couscous, grinding flour to make bread; wood for building, wood shavings for animal bedding, wood pulp for paper...). We then examined the materials under our field microscope and challenged ourselves to identify the difference between the finely ground salt and sugar crystals.


Waratah's latest pet. We have researched habitat and diet, and identified his gender (males have 6 segmented abdomens, females have 8).
